Triggerfish are colorful marine fish found in warm waters around the world, particularly in coral reefs. They belong to the family Balistidae and are known for their distinctive shape, with a laterally compressed body and a large, triangular head. Triggerfish have strong jaws and teeth, which they use to feed on hard-shelled prey like sea urchins and crustaceans. These fish are named for their unique dorsal fin, which has a "trigger" mechanism that allows them to lock the fin in an upright position for protection. Some common species include the clown triggerfish and the humuhumunukunukuāpua'a, which are popular in aquariums due to their vibrant colors and interesting behaviors.
